Abstract:
In order to analyze nutrition and function of Chinese coarse cereal wine,amino acid composition and total polyphenol content of Chinese foxtail millet wine,Chinese oat wine,Chinese quinoa wine and Chinese common millet wine were measured using national standard method and Folin- Ciocalteu assay,respectively. Besides,the antioxidant activity of four kinds of Chinese wine was also evaluated by 1,1- diphenyl- 2- picrylhydrazyl( DPPH)radical,2,2'- azinobis( 3- ethylbenzothiaz- oline- 6- sulfonic acid) diammonium salt( ABTS+·) scavenging assay and oxygen radical absorbance capacity( ORAC) assay. Results showed that the amino acid content of Chinese foxtail millet wine was the highest while Chinese millet wine was the lowest. Total phenolics content showed a decreasing order from Chinese quinoa wine,Chinese foxtail millet wine,Chinese oat wine to Chinese millet wine correspondingly.As to antioxidant activity evaluation,Chinese quinoa wine showed stronger DPPH free radical reducing capacity than others. Chinese foxtail millet wine exhibited the strongest antioxidant capacity in ABTS+·scavenging assays and ORAC assays.In conclusion,Chinese rice wine made by foxtail millet,oat,and quinoa exhibit great advantages than the traditional one( made by common millet) in terms of amino acid content and antioxidant property.These coarse cereals can be used as raw materials for functional Chinese rice wine.
